J OEL T. HARDIN AND JAMES G. CLABK, OF FINTVILLE, TENNESSEE.

T 0 aZZ whom t may concern:

Be it known that we, J on-L T. HARDIN and JAMns G. CLARK, citizen of the United States and subject of the King of England, respectively, residing at Flintville, in the county of Lincoln, State of Tennessee, have invented a new and useful *vVashing-Wachine, of which the following is a specification.

The device forming the subject matter of this application is a washing machine and one object of the invention is to provide a main roller of novel form, the roller being of hollow construction, and being perforated, so that, as the roller exercises its function, the water may flow therethrough as the garments are operated upon.

Another object of the invention is to provide novel means whereby the main roller is yieldably supported for rotation, and is made to coperate with the auxiliary and supplemental rollers which are located below the main roller.

further object of the invention is to provide novel means for assembling` the washing machine with a tub or like receptacle.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the 'present invention appertalns.

lVith the above and other ob `ects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing z-Figure 1 shows the invention in side elevation, parts appearing in section, the structure being mounted upon a tub which appears in section; Fig. 2 is a bottoin plan of the washing machine forming the subject matter of this application; Fig. 3 is a cross section taken approximately on the line 3-3 of Fig. 1; Fig. et is a cross section taken approximately on the line elf-fi of Fig. 1.

In carrying out the present invention there is provided a base 1 carrying near its ends, bolts received in slots 3 formed in brackets 11 bearing against the lower face of WASI-IING-MACI-IINE.

Specificaton of Letters Patent. Patented Sept, 26, 1916 Application filed December 24, 1915.

Serial No. 68,546.

the` base 1 The brackets 4 terininate at their ends m hooks 5 adapted to engage the upper edge of a tub G. lNing screws 7 are threaded into the extremities of the hooks 5 and co-act with the tub 6 to hold the base 1 thereon. lVing nuts 8 are threaded onto the lower ends of the bolts 2 and serve to bind the inner ends of the brackets 4 against the lower face of the base 1.

From the foregoing it will be obvious that the brackets 4 may be adjusted longitudinally of the base, whereby the washing machine herein disclosecl masy be adapted for tubs of different diameters.

Attached to and rising from the base 1 adj acent its ends are 'standards or end plates 9. Extended through the end plates 9 are securing elements 10 rwhich may be bolts or 'rivets, these members serving to prevent the end plates 9 from splitting or warping, when the end plates are made of wood. In the upper ends of the plates 9, slots 11 are formed, amain shaft 12 being detachably journaled in the slots 11. The rain shaft'I 12 is provided with a Crank 30 or other suitable means whereby a rotation may be imparted to the shaft. The ends of the main shaft 12 protrude beyond the standards 9 and are engagedby hooks 14: assembled with the upper ends of retractile springs 15, the lower ends of` which terminate in eyes 16 passing downwardly into openings 17 formed in the base 1 near to the ends thereof. Securing elements 18, which may be bolts or rivets, pass through the base 1 near to its ends and cross the openings 17, the securing elements 18 passing through the eyes 16 which are located at the lower ends of the Springs 15. The securing elements 18 therefor exercise two functions, since they constitute at once a means for retaining the Springs 15 and for preventing a warping or splitting of the base 1, when the same is made of wood.

Supported on the main shaft 12 and located between the standards 9 is a main roller 19, ordinarily but not necessarily fashioned from wood, the eXterior surface of the main roller 19 being provided with corrugations 20 disposed in a long, gradual spiral about the roller. The main roller 19 is hollow and embodies an internal Chamber 21. In the wall of the main roller 19 between the corrugations 20 are formed perthe ends of the main roller 19, as shown at 23, thereby forming Shoulders 24 against which abnt end plates 25, having openings 2C- communicating With the chamber 21, the end plates 25 being held in place by means of screws 27 or the like. The end plates are equipped with hubs 28 and it is in these hrzbs that the main shaft 12 is immediatciy received, the huhs carrying set screws 29 engaging the main shaft 12, to the end that the main shaft and the main rollei` 19 may be connected for simultaneous rotation through the medium of the crank 30 or its equivalent.

Disposed below the main roller 19 are auxiliary rollers 31, provided at their ends with shafts' 82 journaled in the standards 9. The auxiliary rollers 31 lie between supplemental rollers provided With shafts 34 journaled in the end standards 9. The supplemental rollers 33 are 'somewhat larger in diameter than the auxiliary rollers 31.

In practieal operation, the brackets 4: are slid endwise for adjustment, and are held in adjusted positions by the Wing nuts 8, so that the hooks 5 will coperate with the Upper edge of the tub 6, the screWs being tightened np to hold the machine on the tub. The roller 19 is rotated through the medium of the main shaft 12 and the orank 80, the shaft 12 rotating in the slots 11 of the standards 9. The main roller 19 is draWn downwardly by the action of the springs'l. The garments to be washed are guided by the supplemental rollers 33 between the auxiliary rollers 31 and the main roller 19. The Water carried by Vthe garments is squeezedout and fiows. along With Copies of this patent may be obtained for five cents each, by addressing the Gommissioer ofV Patentl, a

the dirt in the garments, through the-per- 1 forations 22 in the main roller 19, into the Chamber 21, and out of the Chamber through rnents is eifeeted, With a minimum expenditure of effort.

For convenlence in claimlng the lnvention, the standards 9 and the base 1 may bev described as a supporting structure.

Having thus desoribed the invention, What is claimed is i A Washing machine comprising a 'supporting structure; a roller journaled for rotation in the supporting structure; and opposed means wherewith the roller coacts; the roller being provided With external, spirally disposed ribs defining grooves therebetween, and being hollow, there being perforations in the roller at the bases of the grooves, the perforations extending in lines which are disposed longitndinally of the roller, and the perforations of each line being spaced apart, the perforations communicating With the interior of the roller; and` JOEL T.
